What Happened

Vincent Armusewicz, 82, of Water Mill, was killed in a single-vehicle crash on Express Drive North in Islandia on Wednesday, January 14 at 12 p.m., according to Suffolk County Police Fourth Squad detectives. Armusewicz was driving a 2023 Chevrolet Colorado when his vehicle left the roadway and struck a tree, police said.

The crash occurred on Express Drive North, with investigators currently examining the circumstances that led to the vehicle departing the roadway. Suffolk County Police Fourth Squad detectives are handling the investigation into the fatal collision, which involved only Armusewicz’s pickup truck.

According to police, detectives believe Armusewicz may have suffered a medical event prior to the crash. This preliminary assessment suggests the collision may not have been caused by typical factors such as speed, impairment, or driver error, but rather by a health emergency that prevented the driver from maintaining control of the vehicle.

Following the crash, Armusewicz was transported to South Shore University Hospital in Bay Shore for medical treatment, police said. Despite medical intervention, the 82-year-old Water Mill resident was pronounced dead at the hospital. The extent of his injuries from the tree impact and any potential medical condition that may have preceded the crash have not been detailed by authorities.

As part of standard protocol in fatal motor vehicle crashes, the 2023 Chevrolet Colorado was impounded for a comprehensive safety check, according to police. This examination will likely focus on determining whether any mechanical issues with the vehicle contributed to the crash or if the collision was solely the result of the suspected medical emergency.

The crash investigation remains active, with Suffolk County Police Fourth Squad detectives seeking additional information from anyone who may have witnessed the incident. Police are asking anyone with information about the crash to contact the Fourth Squad at 631-854-8452.

Location & Road Context

Express Drive North in Islandia serves as a significant thoroughfare in this Suffolk County community, connecting residential and commercial areas. The roadway where Armusewicz’s vehicle struck the tree runs through a section of Long Island that has seen considerable development in recent decades, with Express Drive serving local businesses and providing access to nearby residential neighborhoods.

Islandia, located in central Suffolk County, sits along major transportation corridors including the Long Island Expressway and Sunrise Highway. The community’s road network serves both local traffic and commuters traveling between eastern and western parts of Long Island, making thoroughfares like Express Drive important components of the regional transportation infrastructure.

The ongoing investigation by Suffolk County Police Fourth Squad detectives will likely focus on confirming whether a medical emergency preceded the crash. Given the preliminary belief that Armusewicz may have suffered a medical event, investigators will coordinate with medical personnel to determine the exact sequence of events leading to the fatal collision.

The vehicle impoundment and safety inspection represents standard procedure in fatal crashes, allowing investigators to rule out mechanical failure as a contributing factor. With the investigation still active, detectives continue to seek witness accounts or additional evidence that could provide clarity about the moments before Armusewicz’s vehicle left Express Drive North and struck the tree.

Broader Impact

Medical emergencies while driving represent a significant challenge for older motorists, particularly those over 80 who may be managing multiple health conditions. The suspected medical event in this case highlights the complex intersection of aging, health conditions, and driving safety that affects many Long Island families as the region’s population continues to age.
